Abstract

The compressibility of nitrous oxide (N2O) has been measured with high precision from 0° to 150°C and over a density range of about 18 to 180 amagat. The agreement with results of others using somewhat different experimental techniques is good. The virial coefficients are calculated, and the intermolecular potential of nitrous oxide calculated from the second virial coefficient for several forms of force laws, both spherical and nonspherical. A comparison with the physically similar molecule carbon dioxide is made.
